my wife has always swallowed .. two of her girlfriends over the years she found wont have any oral sex with their husbands either way .. as a result the scene was set and she manipulated a situation with husbands without the wifes being aware and gave them blow jobs as well as let them eat her out .
40 years later they are still indulging on a regular basis . in fact they do everything that their wives wont indulge like roleplaying , group , bondage and anal sex .
everyone is happy including me and has definitely made a strong marriage for us .
